Is there any way to do this? 回答1: You cannot append to an existing xlsx file with xlsxwriter . There is a module called openpyxl which allows you to read and write to preexisting excel file, but I am sure that the method to do so involves reading from the excel file, storing all the information somehow (database or arrays), and then rewriting when you call workbook.close() which will then write all of the information to

It's possible with xlsxwriter to save variables to existing excel files and read them after, though the problem is that the variables are stored as strings in my excel file. Let's say I have a list of many different variables with various types (pd.datetimerange, pd.df, np.arrays, etc.), if I save them to the excel file the variable type would be lost. Also the Python script is called from my Excel file so I can't change anything in it without writing a VBA script. Which would temporarily close my workbook, dump the chars (with say pickle strings) and reopen it. Is it possible to retrieve the

I am trying to create an export to excel functionality in my django view as follows: def export_myreport(request, sd, ed): from xlsxwriter.workbook import Workbook import cStringIO as StringIO from django.utils.encoding import smart_str # create a workbook in memory output = StringIO.StringIO() wb = Workbook(output) bg = wb.add_format({'bg_color': '#9CB640', 'font_color': 'black'}) bg2 = wb.add_format({'bg_color': '#FFFFFF', 'font_color': 'black'}) ws = wb.add_worksheet('My Report') row_num = 0 summary = MyModel.objects.filter(time__range = (sd, ed)).select_related() row_num += 2 row = [ smart

I want to merge several series of cell ranges in an Excel file using Python Xlsxwriter, I found the Python command in the Xlsxwriter documentation in this website http://xlsxwriter.readthedocs.org/en/latest/example_merge1.html as below: worksheet.merge_range('B4:D4') The only problem is that I have my ranges in row and columns numbers format for example (0,0) which is equal to A1. But Xlsxwriter seems to only accept format like A1. I was wondering if anybody else had the same problem and if there is any solution for that. Almost all methods in XlsxWriter support both A1 and (row, col) notation

I am formatting all of my columns in an excel file using the xlsxwriter module: def to_excel(video_report, feed): # Create a Pandas Excel writer using XlsxWriter as the engine. writer = pd.ExcelWriter('daily_report.xlsx', engine='xlsxwriter') # Convert the dataframe to an XlsxWriter Excel object. video_report.to_excel(writer, sheet_name='Video Overview', na_rep="-") # Get the xlsxwriter objects from the dataframe writer object. workbook = writer.book worksheet = writer.sheets['Video Overview'] # Add some cell formats. integer = workbook.add_format({'num_format': '0', 'align': 'center'})
